How do I resize this jpeg with Elements 12?

Report · Jan 16, 2017

I have a 300 dpi jpeg, 3281 pixels on longest side, with file size of 21.7 MB. Need to resize to 72 dpi, no fewer than 1920 pixels on longest side and a maximum file size of 5 MB. How do I do this with Elements 12?

Two solutions:

- A - First use the Image > Resize > Image size once without checking 'resample' and setting the dpi to 72

Then use the same dialog again with all three options including resample checked, and set the width to 1920 pixels

- B - Create a new empty document with the right size and dpi

Then open the file to resize and move it from the photo bin to to the empty document, adjust the size with the move tool. When done, flatten and check the size.

Hello Michel,

Thank you very much!

I tried Solution A (Solution B is beyond my capability). I did what you said, setting the length (the longer dimension) to 1920 pixels. However, the total file size came to 7.43 MB, and it cannot exceed 5. Did I do something wrong?

I hope you can offer a suggestion,

Leslie

You are right, I did not mention the resizing in MB.

Once you have set your dimensions in pixels, the solution to get the correct size is to use the ability for jpeg files to 'compress' the size in kilobytes for the same amount of pixels. When you 'Save as' jpeg format, you can choose the 'quality level'.

If you get 7 MB, you are probably saving in .psd format which is not compressed.

You might save with the other file format: tiff with lossless compression to stay under 5MB.

No, I was saving in jpeg. And it's the required format, the only one accepted by the gallery where I'm applying.

Even at the maximum 12 quality, a jpeg with your requirements should be under 5 MB. I never use more than level 10 which typically gives 1.5 MB. The size depends very much on the amount of detail and especially on noise.

Unfortunately, it did not work that way for me. I tried saving in jpeg high, medium and low, as well as saving for internet, and the file size was always the same, over 7MB. It was a photograph of a painting that I was trying to reconfigure and send, ironically titled Tout Va Bien.

That's not possible.

Apply the required resizing to one of your images.

Check the result.

Use 'save as' to create three different images with compression (quality) 2, 10 (recommended) and 12 and put them on the desktop or the same folder. What size in MB seen in the explorer?

My results: 216, 1 262 and 3 409 KB.

For the fun, I added a sandstone texture filter plus 12% noise... result: 11 598 KB

Sorry to have taken up your time, Michel. I worked several hours on this insanity this morning. Followed your directions. I even used a different image (to change my luck? In case the first one was cursed?). Using Elements, the image was 72 dpi, 1920 x 1208 pixels, saved as highest JPEG—6.64 MB. (Saving at medium or low JPEG did not change the file size, as before.) But when I saved the image to the desktop as you suggested, I opened it with Preview and checked the file size. It was 127 KB. So I’ve just given up on this. I know someone here (NY) who might be able to help me. If not, so be it.

Many thanks for your efforts,

Leslie

Another way not mentioned is to use File>Save for Web where you can resize and see the file size when saving as a Jpeg.

Regular File>Save As>Jpeg might not differ in file size when changing compression settings if the file in question has lots of metadata.

File>Save for Web removes all the metadata and while technically it doesn't set a resolution, since the metadata is removed, most applications/programs will read the resolution of the file as 72.

Anyway, try File>Save for Web

https://helpx.adobe.com/photoshop-elements/using/optimizing-images.html

First though make sure your image is sRGB by going to Image>Mode>Convert to sSRG Profile.

This insures your image will look as close to the way you see it on most peoples computers or devices.

And check Embed Profile in the Save for Web dialog.

When looking the file size in save for web, remember 1024 KB or K (kilobytes) = 1 megabyte.

Very smart!

I did not think about that point of file resolution requirements.

It seems that the ppi requirements are obsolete ones based on old versions of layout programs. Anyway the only meaningful criteria for sharing digital images should be the pixel size, not the ppi or the mm/in dimensions.

Many thanks, R_Kelly! Finally, success!!
